The Western European network opposes what it says are increasingly restrictive harmonisation of asylum and immigration policy in Europe, and aims to build alliances among migrant laborers and refugees. Common slogans used by the Network include; "No Border, No Nation, Stop Deportations!" and "No one is illegal."[2]

No Border Network has existed since 1999,[3] and its website since 2000. The No Borders Network in the United Kingdom claims to have local groups in 11 cities.[4]

In February 2010 No Borders groups from the UK and France opened a large centre for refugees sleeping rough in Calais, France, under the name "Kronstadt Hangar".[22]

Calais authorities have accused "extremist activists" within to the No Borders network of being "driven by an anarchist ideology of hatred of all laws and frontiers" and engaging in, and encouraging, violence and harassment against French police and social workers at the Calais Jungle migrant camp, as well as "manipulating" and "misleading" the migrants living there.[23]
